EDMUND B. ANGELL, 0F DERBY, NEW HAMPSHIRE.

ACETYLENE-GENEBATOR.

To all whom it may concern Be it known that T, EDMUND R. ANGELL,

a citizen of the United States, residing at Derry, in the county of Rockingham and State of New Hampshire, have invented a new and Improved Acetylene-Generator, of

which the following is a specification.

It belongs to that class of acetylene generators known as carbid-feed, in which calcium carbid, in small quantities at a time, is automatically dropped into water.

The object of my invention is to produce an acetylene generator for service out of doors in winter as well as in summer.

In this application T do not claim the mechanism for feeding carbid, as this is shown and claimed in my copending application Serial No. 387215 filed Aug. 5, 1907.

T accomplish this in the following manner:

Figure 1 is an elevation of my device. F 2 is a vertical section of it. Fig". 3 is a sectional view taken on the line 8 And F is a sectional view in the plane 4 l.

Like reference letters represent correspending; parts in the seve a1 figures.

A. and B represent two concentrically lo cated hollow cylinders, and C, the gasholder floating: in suitable liquid in the annular space between them. The annular disk D, fastens the two cylinders together and forms the bottom of the annular space between them, which is the gasholder seal.

E is the carbid chamber, or hopper. It is formed by the upper part of the cylindrical shell B, and a frusto-conical bottom. Its small end is the mouth of the carbid chamber, or hopper, through which carbid drops. It is closed by a conical valve F, which is attached loosely, by a ball and socket joint, to the rod G, which is suspended from the lever H by the pivot I. The lever is pivoted at J to the support K. The over-counterpoising' weight L, is pivotally suspended from the short arm of the lever, and its lower end slides vertically in the guide N. The cover it, togethe with the support K, and a casing, prevents carbid falling into the gas chamber M.

S is a guard sleeve rigidly fastened to the support K, surrounding a portion of the rod G to keep the carbid from impeding its motion.

T is a disk lying upon the top of the sleeve S. The rod G slides through it Specification of Letters Patent.

may be held suspended whenever desirable.

F is a guard thimble to prevent moisture running down the lower surface of the hopper upon the valve F.

is a base, or bed-ring, an iron ring rabbeted on its .pper inner edge, and on its lower surface. The inner wall of the gasiolder seal, which is the cylinder B, extends below the bottom D of the seal and is fastened to the inner surface of the iron ring G so that the cylinder B and the rabbet on the upper face of G form a gutter H which is rectangular in cross section on circling the machine. The bottom, D, of the seal is above the gutter by a small space, so that the whole top of the gutter is open. This construction allows free access for water to the gutter, to flow around it and escape by the outlet J.

I is a dam across this gutter and J is the outlet from it.

K is a packing ring in the groove of the lower rahbeted surface of the iron ring G.

M is the detachable generator pail and its top edge is adapted to secure a tight joint with the packing ring K.

L L are lugs fastened to the pail M on diametrically opposite sides, and near its top.

N N N are legs to support the machine. They are fastened, at points of one hundred and twenty degrees apart, to the iron ring G and to the hoop O, by means of cap screws.

Q, is a bail-shape lever. It is pivoted at each end to one of the legs N at P P, Fig. 3. Equally distant from the pivoted ends of this lever and on diametrically opposite sides of the machine, two depending hooks R facing in opposite directions, are fastened to the lever, adapted to engage the lugs L L on the pail M. An eccentric S, proviced with a handle, is pivoted to the lever at its center and opposite the third leg N, adapted to work against the shelf T, which is attached to the iron ring G and extends outwardly beyond the leg.

d is an adjustment screw working through the snelf T, and against the eccentric S. Its service in conjunction with the eccentric, is to adjust the tension of the lever Q. By the operation of the eccentric, the bail-shape lever is forced up or let down, so that the top of the pail id is caused to press tightl against the packing ring K", or released therefrom. hen the pail is released from the packing ring, it can be completely removed by giving it a slight rotary motion to disengage the lugs L L from the hooks R R, since they face in opposite directions. The pail is secured in place by reversing the operation.

U is a frusco-conical pipe fastened to the frusto-conical bottom of the carbid chamber, and around its mouth. It extends downwardly nearly to the iron ring G, and

is there tightly connected with the cylinder 1% by means of the annular ring V. The space within the cylinder B, frusto-conical pipe U, annular ring V, and bottom of the carbid chamber, constitutes the gas chamber M.

Y is the gas exit, or service pipe, leading from the gas chamber.

TV is a filter pocket placed within the chamber M and over the inner end of the service pipe.

K is the entrance to the pocket, through which filtering material is introduced and removed.

The operation of the device is as follows: The generator is installed by placing it upon a level foundation and connecting it with the piping of the house. Then the gasholder seal is filled with suitable liquid. One of the detachable generator pails (they are furnished in duplicate) is nearly filled with water and secured in place in the manner already described. lVhen both the gasholder and screw TV are in their lowest position, the disk V holds down the long arm of the lever, so the mouth of the hopper is open. But, if now the screw W is turned up to its highestposition, the disk V will be raised from contact with the lever H, and the over-counterpoising weight L will seat the stopper F, closing the feed. While the feed is thus closed, the charge of calcium carbid is introduced into the carbid chamber through the nipple O, and the cap P screwed on. The screw lV with its transverse disk, together with the lever H pivoted at J, the oVer-counterpoising weight L, and stopper F pivotally suspended from H by the rod G, provides means both for closing the feed from the outside, so that calcium carbid can be introduced into the carbid chamber without falling through it, and for causing the initial action of the feed from the outside. Without the screw EV with its transverse disk controlling the feed as described, the device would be inoperative and worthless. hen the screw is turned down, after carbid is introduced into the chamber, some of it is caused to fall into the water contained in the detachable generator pail, the resulting gas raises the gasholder and the machine is then in operation. The gas, from the detachable generator pail, passes up through the pipe U into the carbid chamber through the space between its mouth, and the stopper F. In passing through the carbid in the hopper it is dried before it reaches the gasholder. From the gasholder it enters the gas chamber M through the opening around the weight L. Thence it passes through the filter N into the service pipe.

The use of the gas chamber is to counteract the effect of air which enters the generator when the detachable pails are eX- changed. It does this both by blocking out some of the space which air could readily enter, and by overbalancing, by its volume of gas, the small quantity of air which does enter, Should it be desirable at any time to detach the generator pail for any purpose, or to remove the cap P when the gasholder is up, either to introduce more carbid, or ascertain whether much remains in the carbid chamber, the chain link near the 1001: E is first attached thereto to keep the holder suspended, and then the cap is removed. In freezing weather, the detachable generator freezes to the gasket. It is thawed therefrom by pouring hot water into the gutter H to flow around it. Then the pail can be detached and the residuum easily removed after pouring warm water upon the outside of the pail.

Having thus fully described my inven-' tion, I claim as new and desire to secure by Letters Patent the following:
